ROBERT TUTTLE MORRIS, OF NEW YORK, N. Y.

SMOKERS IEIIPE.

To all whom it may concern:

Be it known that I, ROBERT T. Monms, a citizen of the United States, and a-resident of the borough of Manhattan, city, county, and York, have invented "certain new and useful Improvements in Smokers Pipes, of which the following is a specification, accompanied by drawings. a

This invention relates to improvements in smokersv articles, more particularly to tobacco pipes, and the object of the invention is to avoid the abundant condensation. of disagreeable tars and steam in the lumina of the bowl and stem, thus obtaining a comparatively dry pipe and obviating the necessity of frequently cleaning the pipe or blowing out the accumulated moisture.

To these ends the'invention consists of the pipe, substantlally as hereinafter fully described and claimed in this specification and shown in the accompanying drawings, in which Figure l is a longitudinal sectional elevation of a pipe embodying the invention; and Fig. 2 is a transverse sectional view on the line 2--2 of Fig. 1 looking in the direction of the arrows.

When tobacco is burne d in a pipe there is a destructive distillation in process. Steam from the water content of the tobacco, smoke, various tars, volatile products and nicotin combine to make a vapor which is drawn into the mouth of the smoker. In a pipe of ordinary construction, this vapor on leaving the hottest part of the pipe undergoes condensation in various 'degrees inthe cooler tobacco beneath, and upon the cool walls of the bowl and stem. There is agreater degree of condensation upon the cooler parts of the interior of the stem. This condensed vapor is popularly believed'to be saliva entering the stem from the mouth of the smoker, but I- have discovered that in fact almost no saliva enters the stem. Efforts at disposing of the uncomfortable degree of moisture in pipes have been based upon a wrong conception, including this idea that the moisture comes from the mouth of the smoker. I have found, however, that this moisture practically all comes from condensation of steam in the cooler parts of the pipe at a distance from the burning point.

According to my invention, I limit the condensation of the products-of combustion by abstracting heat from the'zone of combustion, and distrib-lting saidheat through Specification of Letters Patent. I

out the lumina of the bowl and stem, thus tending to maintain the vapors arising from combustion in vaporous form and thereby substantially avoiding the deposit of products of combustion. I conduct the heat from the hottest part of the pipe to the other parts of the pipeand maintain the walls of the lumina of the bowl and stem at a suflicient temperature to limit condensation to the desired degree. It is not desirable to have an absolutely dry pipe, for in that event the flavor imparted by sweet wood, as in the brier wood pipe, is lost.

'Rcferring to the drawings A represents the bowl of a suitable pipe, and Bis the stem which in this instance is shown as an ordinary push stem, although the invention may be used in connection with any pipe to which it-is found applicable. In order to conduct the heat from the hottest part of the pipe, I provide a conductor G preferably in the form of a metallic wire of any suitable metal extending substantially throughout the'bowl and stem. The bowl may be provided with a' groove or depression D in which the conductor is laid and the conductor may be held'in place by one or more staples D. Preferably the conductor C, terminates at E beneath the top of the bowl atone end andterminates at the other end F adjacent the mouth orifice of the stem. That small part of the stem between the end of the conductor F and the-mouth orifice is kept warm byactual contact with the lips of the smoker. The conductor may be inserted at any con nient position in the bowl of the .pipe and-I am not to be limited to the location of the conductor shown in the drawings. c

The device I have described accomplishes the objects of this invention in a practical manner. The heat from the hottest part of the pipe at the zone of combustion is conducted through the conductorO to the cooler parts of thepipe and distributed throughout the lumina of the bowl and stem, thereby maintaining a vaporous condition of the steam, smoke and the various volatile products of combustion. I have found by-actual demonstration and test that the conductor does actually take up theheat at the hottest part of the pipe, and conduct said heatthroughout the length of the lumina of the The'vapor in the pipeis actually maintained in avaporous state, thus :limitingthe condensation to, such a degree PatentedMay7,1912.

Application filed November 30, 1910, Serial No. 594,937. Renewed December 27, 1911.

a practically pipe is obtained. The plpe 1s therefore'less disagreeable. in odor.

, and combustion is more com lete inthe to bacco, because the wetting-o the tobacco in the cooler parts of the bowl by condensing vapor is avoided. The bowl of the pipe is rendered somewhat cooler, owing to the distribution of that portion of the heat con-' with the hottest portion of. tobacco undergplng combustiomand distributes the heat om the hottest part by conduction through the rest of the pipe, thus tending to maintain the vaporous condition ofproducts of combustion until they have reached the mouth of the smoker. Since the conductor distributes the heat-throughout the. course 'tically avoids condensation of the vapor in followed by the vapor, the efiect is to keep the vapor ata degree of tension which practhe cooler partsof the pipe. The smoke on I reaching the mouth seems sweeter and less pungent, beeause'o its high moisture content and because it carries in ,vaporous form var ous fragrant products of 'COIIlbIJSlJlOIl,

. which in pipes of ordinary construction are precipitated by condensation upon the cool walls of the'lumina of the bowl and stem and upon the) cool tobacco in the bottom .0

the bowl. In accordance with my invention, so little tar and nicotin is deposlted in the pipe that cleansing is'largely done away with. I concentrate the heat as far as possible within the pipe itself in order to maintain the vapors in vaporous condition, and the conduc- I tor is arranged wholly within the pipe, thus I distributing the heat within the pipe. My

invention has been foundv to operate satis factorily and well.

I cla1m and desire to obtain by Letters Patent the following:

1. A's'moki'n pipe, comprising in combinationwith t e bowl and stem, of means for conducting heat from the hottest part of the pi e and distributing it throughout the restro' the pipe, thereby afiording means for talns so much moisture maintained in a maintainin the va ors arising from com bustlonun er a su c1ent degree of tension to 11m'1t condensation and substantially bu'st on. V I I 2; 'A smoking pipe, comprising in comavoiding the deposit of products of com- 'bination with the bowl and stem, of means located within the luminaof bowl and stem for conducting heat from the'zoneof combustlon andtdistributing-it throughout the :rest of the pipe, thus tendingto maintain the vaporous conditio of the products of combustion until they. have reached the mouth orifice of the stem. v

-3. A smoking pipe, comprising in combination with the bowl and stem,aof a heat conductor extending throughout the bowl and stem and adapted to distribute the heat throughout the. lumina of'bowl and stem thus maintaining a vaporous condition 0 the steam and volatile products of combustion and limiting the precipitation of said 76 products in the bowl and stem.

4 A'smoking pipe provided with a conductor'of heat in thelumina of the bowl and stem and extending into the zone of combustion, thus'limit-ing condensation of the Va- 80 pors arising from combustion and maintain- 'ing the bowl and stem substantially free from deposited products of combustion.

said conductor being adapted to conduct the heat from the'hottest part of the pipe at the. zone of combustion and concentrate and dis tribute said heat Within the pipe throughout the l'umina of the bowl and stem, thus tending to maintain the vapors laden with products of combustion at a suflicient degree of 96 tension to limit condensation and substantially avoid the accumulation of deposits in the lumina 6f the bowl and stem.

In testimony whereof I have signed this specification in the presence of two subscrib- 100 ing witnesses.
